Patented Sept. 29, 1908.

Application filed'December 9, 19137. Serial No. 405,674.

Be it known that 1, CHARLES H. MILLER',

a citizen of the United States, residing at Cleveland, in the. countyof Cuyahoga and State of Ohio, have invented certain new and useful Improvements in a Combined Coal and Gas Ran e, and do declare that the following is a'fu l, clear,'andexact description of the invention which will enable others skilled in the art to which it appertains to make and use the same. i My invention relates to a combined coal and gas range, and the-object of the inven-' tion is to provide a range adapted to use either solid fuel or gas or vapor for heating the oven, all substantially as shown and described and particularly pointed out in the claims.

or drawings, Figure 1 is a, perspective front elevation of the range with the front plate broken away, and Fig. 2 is a cross section thereof from sidejto side, Fig.1, showing the burner in closed position,

and Fig. 2 showing the-same open. and. in

using position.- Fig. 3 is a front to rear cene tral sectional elevation'with the parts in position as seen in Fig. 2. ,Fi tive detail of a portion of 51G vapor burner and a rear damper operatively connected therewith. 'Fi 5 is an enlarged cross section of the gas burner and parts-of the range immediately associated therewith and with the burnerv in open or using position. Fig.6 is a cross section of the range and on the axis ofthe burner partly broken out int'erm'ediately on line corresponding to. 6, 6, .Fig 5.

As thus :shown, A re resents the body of the ra e, F the usual repot, it the ash it, and O t e oven located as usual inkitc en ranges with a draft flue D -aboutathe same,

top, bottom and sides. -Afresh air draft or passage Ev is provided across-the bottom of the range, beneath the bottoin wall or floor of said hot air draft space D through which fresh air is drawn to supplycombustion for both the firepot and the gas burner.

If hard fuel, like coal or wood be used, the

. burner B is closed by rotating the same aquarter turn into 'closed position, as in Fig. 1,

but if said burnerbe in use draft through the fire-box is cutiofl by a rear top damper 2 through which a short draft is provided into the smoke flue G and by a down damper 3, adapted to close the draft space D downward 4 is a, perspecl at the side of the oven, thus cutting off all draft through the fire pot when gas is burned.

pers 2 and 3, or either of them,'ifl'ay be open or be wanted, and said dampers have separate control. The said gas burner B has trunmom 4 at its ends on which it is adapted to make a quarter rotation, and is located in the angle of the inner wall 8 of the ashpit, the bottom 0 of the oven above the same and the division wall or plate 5 .whicli separates the draft flue D from the fresh air flue or space E beneath said plate. The location of the burner in this particular angle enables a quarter rotation thereof to close all the passages about the same, as in Fig. '1, or to open the passages as in Fig. 2. To these ends the However, if hard fuel be used, the said dam- 1 closed according as a direct or indirect draft burner is provided with a flange 7 lengthwise at an inclination and of such elevation that when the burner'is in closin position and out of use the said flange 7 wil rest against the inner walLS of the ashpit, closing the u ward draft between the burner and the as pit, or between walls 8 and 14, as seen in Fig. 1 Thesaid flange 7 is provided with an a mu 9 at an inclination thereto adapted to orm a stop for the burner on plate 5 and close air draft on that side, and a longitudinal rib 10 on'this apron is adapted to engage in the angle of the plate 12 on bottom oven plate 0 and also close the draft space D against ossible outlet between the two vertical wal s 8 and 14, when the'burner is out of use. The said burner also has another flange, 15, along its bottom and side adapted to engage the edge of thein'termediate. wall or plate 5, Fig. 1, and cutoff draft through this space or channel when the burner is closed.

p The eflectof the foregoing construction is to provide a free passageway at one side of burnerB for fresh eir to supply combustion when the burner is in use, and the flange 7 which stands on the opposite side of the vation to cut off some of the draft from the .burner upon that side and to-induce the products of combustion and heat to pass more or less into the-channel or space between the 'lates 8 and 14 into the oven as 'shown in i 2. a damper H is shown at the bottom 'of ex haust or outlet flue .G beneath the oven at the burner for this passageway has suflicient elerear ofthe raiige, and this damper is auto open for draft from the firepot.

lbjand 22 on the damper.

elusive, the projection or lug 20 bears upon projection 22 of the damper and rotatesit into closing position, but when the burner receives a quarter rotation out of use, the

pro'ection strikes lug 21 on the damper an throws it back and open in the direction -of the arrow, Fig. 6. i The angle 'plate 12 on the bottom of' the 20 oven serves also to protect the oven plate from burning out by the direct heat of the burner, and a stop piece 24 is laid lengthwise with the burner along the ed e of plate 5 to provide a close bearing for flange 15 when 25 the burner is closed.

-Whatever products of combustion enter the even between walls 8 and 14 pass out from the oven through holes 26 at the bottom- 'of rearfalse wall 16 and thence outward by 30 flue openings 27 at the top of the rear main wall 17 Damper plate 3 is right angled in cross sec tion'and therefore adapted to close the oven openings 18 when solid fuel is being usedin firepot F and to open draft flue D when the damper is in this position. When, drawn outward passage or flue D is closed at its top and oven openings 18 are uncovered thus making passage D available for the upward 40 movement of heated air from fluid burner B and thereby exposing the oven at this side and bottom to the heat from said burner. The arrangement of flues and dampers, and location of the, burner and fire pot in respect thereto, are such that a uniform distribution of heat about the oven is always obtainable from either the fluid burner or the fire pot.

What I claim is 1. A kitchen range-having an oven and an angular heat passage about the same, and a combined fluid burnerand damper located in an angle of said passage.

2. A kitchen range having an oven provided with a heat passage beneath the same and a rotatable and combined fluid burner and damper in said passage.

3. A kitchen range having a fire pot and a baking oven and a heat passage beneath the oven, in combination with a rotatable burner in said passage and constructed to open and close the same.

4. A kitchen range having :1. baking oven and a heat passage beneath the same provided with an air intake to supply co1nbustiori, and a rotatable fluid burner in said passage and constructed to close said intake.

5. A kitchen range having a baking oven with a heat passage beneath and at the side thereof, an air inlet from beneath in the angle of said heat passage, in combination with a rotatable burner in said angle eonstructed to open and close both said draft passage and said air inlet.

6.

7. A kitchen range having an oven and an exhaust flue and a draft passage beneath the oven provided with an opening into said exhaust flue, in combination with a rotatable burner in said passage and a damper for said -opening operatively connected with said burner.

8.

9. A combined gas and coal range having an oven and an angular draft llue about the same, a fire pot for solid fuel at the front of said oven, and a "fluid burner in said draft flue at the bottom of the oven. in the angle below the fire pct.

10.

11. A kitchen range having an oven and a heat passage about the same, a lire pot at the front of the range and a fluid burner located in said heat passage, and a righie angled damper plate adapted to control the air draft about the oven for both said fire pot and said fluiil burner.
